A short HDMI and power lead will not reach a mirror mount. Extend that harness 5 feet with the Bully Dog 40010 so a GT, WatchDog, or PMT can sit on a Mirror-Mate. Run the cable to the mount instead of leaving the device on the column.

• Build: This is a 5 foot HDMI and power extension. Bully Dog says it includes the parts needed to extend the GT, WatchDog, or PMT harness, and that it is made for Mirror-Mate mounting products.
• Part number: Bully Dog 40010.
• Fits: GT, WatchDog, or PMT devices when the lead has to reach a Mirror-Mate mount.
• Does not fit: Not a 2018 Ram bypass cable. That part is 42215. The manufacturer page does not name an H&S Mini Maxx or Black Maxx.
• Not in the box: No tuner, no gauge, and no Mirror-Mate mount.

Order today to secure your replacement. Confirm the device is a GT, WatchDog, or PMT, and that you already have the Mirror-Mate mount.
